In 1989 the Voyager 2 space probe flew past Neptune and took the canonical image that we're so used to seeing. BUT the blue colour in that image we're so familiar with is actually a FALSE colour. Not what you'd see with your eyes if you were that close. Now those images have been reprocessed with some new data that allows us to make a TRUE colour image, and it turns out Uranus and Neptunes look more like twins...

I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
